The map above shows temperature anomalies across the Conterminous US for calendar year 2019 through November. These anomalies relate specifically to daily Low temperatures. Where you see red, daily low temperatures were warmer than 20th Century averages (darker reds indicate much warmer daily low temps). Generally speaking, 2019 has been a much warmer than average (vs 20th Century) year, especially in the Eastern US and along the Pacific, Gulf and Atlantic Coasts (where the vast majority of Americans live). The Northern Rockies, Dakotas and western Great Plains areas have seen cooler temperatures but this isn’t as significant for most consumer products businesses because there aren’t as many people in the region.
Why look at daily low temperature anomalies? There could be many reasons but one reason is that some consumer products sell a lot more or a lot less depending on weather. For example, the starter motor in your car is far more likely to fail when the nightly low temperature is really low. So, companies in the automotive aftermarket are accustomed to selling lots of starters in the late fall and winter months when temperatures plummet.
But, what if they don’t plummet? Well, that might lead to lower sales volumes for the starter produce category. It might also leave a lot of starter inventory sitting on shelves at distribution centers. In other words, this can have a major impact on the starter motor supply chain. This appears to be the case in a large portion of the Eastern US where aftermarket companies may have expected lower sales due to milder overnight low temperatures.
